HOSE-COUPLING.

Specification of Letters Patent.

Patented Mar.1o,1914.

j Application led April 9, 1912.' Serial N o. 689,638.

To all whom it may concern: lBeit known that I, JOSEPH R.' KILE, -a citizen of the United States, residing at Neodesha, in the county of Wilson and State of Kansas, have invented certain new an`d useful Improvements in- Hose-Couplings, of which the following is a specification.

This invention relates to hose couplings, the main object of the invention being to provide a simple, reliable and eliicient construction of coupling for connecting the meeting ends of hose sections, and the inembers of which are adapted to be coupled and uiicoupled in an easy and ready manner.

A further object of the invention is to provide a construction of coupler in which the male and`female sections are adapted to .form a water-tight unioirwithout the use of' threads, which admits of the practically instantaneous connection and disconnection of the hose-sections, which is rovidedwith simple and effective means or taking up slack or compensating for wear of the coupling members to maintain a tight joint, lwhich is adapted to hold the coupling members in firm engagement and admit. of the same beingrigidly locked together when required, and which is adapted by slight modification for either high or low pressure service.

The invention consistsof the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing` in which Figure 1 is a view in side elevation showing two sections of a hose united by my improved coupler.I the parts being respectively shown in side elevation and longitudinal section below and above the line )iw-X. Fig. 2 is a longitudinal section of the same. Fig. 3 is aface view of the spring Washer. Fig. 4 is a sectional view of thesame.

The coupling comprises two main members, to wit: a male member 1 and a female member 2.- The member l is provided with a smooth cylindrical outer end 3 for insertion within a corresponding socket 4 in the member 2, and is also provided with a circumferential fiange or enlargement presenting at one side a straight shoulder 5 and at its opposite side a beveled. shoulder 6, which latter is adapted for engagement with a beveled surface 7 at the inner end of the member 2, to form a water-tight joint or union. The outer ends of the respective sections 1 and 2 are prolaterally in opposite directions.

vided with externally threaded inner portions 8 and beveled serrated or toothed outer portions 9, which latter are adapted to receive the meeting ends of the hose sections 10` T lie.- member 2 is provided with two sets or series of lugs or projections 11 and 12. the outer series of lugs 11 being adapted forengagement by the fingers or a wrench to facilitate the connection and disconnection of the main coupling elements, while the lugs or `projections 12 are adapted for use in conjunction with a coupling sleeve or member 13to lock the said two main coupling sections or members 1 and 2 together. The sleeve '13 is adapted to snugly embrace the meeting portions of the sections 1 and 2 and is provided at one end with an inturned flange 14 adapted to come opposite the shoulder 5 when the parts arecoupled togcther. Said sleeve 13 is provided at its opposite end with a series of bayonet slots 15 for engagement and coperation with the lugs 12. The outer walls of the transverse or circumferential portions of said slots are scalloped to provide a 'series of seat-recesses 16 in which said lugs 12 may rest to more 'securely retain the coupling sleeve in position and hold it against retrograde movement and disconnection.

Disposed between the shoulder of the member 1 and flange 14 of the sleeve 13 is a spring washer 17 having a plurality of angular faces alternately bent or defiected As shown in the. present instance, the spring washer is of octagoiial form, and its alternately bent angular portions or faces are adapted to bear respectively at their points of union against the said shoulder 5 and flange 14 to hold the sleeve 13 in locking engagement with the lugs 12 and the faces 6 and 7 of the members 1 and 2 in close contact, so that an absolutely water-tight joint or union will be produced. The spring is adapted to take up any play or looseiiess of the parts due to ywear or other causes, and thus automatically make the connection water-tight atV all times.

Adjacent to the shoulder 5 'and flange 14 the member 1 andsleevel are respectively provided with recesses 18 and openings 18 .adapted to register when the parts are coupled together, so that the points of a spanner wrench or suitable locking plugsor keys may be inserted therein to rigidlyhpld the parts connected,k against any possibility L.of

casual disconnection, a special and effective provision against relative movement and leakage when the coupling is usedin connection with high pressure conductors. This construction also enablesthecoupling members to be held fixed against movement While the sleeves 19 are being screwed on or off. v

The meeting ends of the hose sections 10 are slipped upon the beveled and serrated ends 8 of the members 1 and 2 and are adapted'to be held firmly clamped thereto by clamping members 19, each comprising a tubegorssleeve having wrench engaging lugs 20. Ihe inner end of each clamping member has an internally threaded portion 21 to engage the threaded ortion 8 o the coupling member to which 1tl is applied and a beveled surface 22 toengage the end of the hose land crowd and clamp the same agamst the beveled and serrated surface 9 of the coupling member to which it is apl plied, thus firmly holding the end of the hose 'against any possibility of disconnection. These clamping members are particularly designed for high pressure service.

In the A'operation of unitin the meeting ends of hose sections provide with my improved coupler the meeting portions of the .sections 1 and 2 are broughtinto approxi` mate relation,` the sleeve 13 adjusted so that the entrancel ends of the bayonet slots 15 will register with the lugs'12, and the parts brought together so that the end 3 of the section 1 will fit Within the socket 4 of the 'section 2 and the lu 12 within the outer ends of the slots 15, after which by `-turning` the sleeve 13 until the lugs 12 are brought to the desired degree Within the inner end.` of said slots 15 the joint-closing surfaces 6 and 7 of the members 1 and 2 will be brought into abuttingrelation. .In this op eration the spring 17 will` be compressed andby its tendenc to react will hold the parts firmly assem led and the lugs "12 in enga ementwith the seats 16, so as to avoid possi ility of casual retrograde`motion of the sleeve 13 and loosening or disconnection of the cuplin members. Where it is desired to lock t e members 1 and 2 rigidly together to prevent the sleeve from turning while the coupled hose sections, for instance, are'being drawn alongthe ground Vor manipulated, this may be accomplished by irlsei-ting key plugs or the points of a spanner Wrenc within the registering recesses 18and openings'18. To unco'uple the sections it .is simply necessary to turn the sleeve 13=back untilthe lugs 12 again register with the entrance ends of the slots 15, whereupon the hose sections may be released from engagement with each other, which action will be promoted by the expansion of the spring 17.

It will be observed that by the construction described the use of threaded surfaces between the partsI i, 2 and 13 is avoided, and that the construction of the fastening connections is such that the sleeve 13 may be easily and conveniently adjusted to locking and releasing position wit-hout the use of tools.

Having thus described the invention, what I claim as new is A hose coupling embodying male and female sections having telescoping cylindrical portions provided with conical abutting Vfaces extending to the periphery of the sections, one of said sections having an abutment shoulder and the other diametrically disposed locking lugs, a coupling ring uniting said sections and closing the joint between said conical abutting faces at the pe# riphery of said sections, said ring -being provided at one end with a iange opposing said shoulder and at its opposite ends with cam slots formed with corrugated outer walls to interlock with said lugs, and a ringshaped fiat metal spring disposed between said Bange and shoulder and having angularly related portions alternately bent in opposite drectlons and respectively bearing on Vthe fiange and shoulder, said spring serving to force the flange away from the shoulder and thereby exerting endwise pressure on the sleeve to hold the conical faces 4in close contact andv also maintain the corruv gated'walls. of the cam slots in interlocking engagement with the lugs, substantially as described.

. In testimony yvhereof I aix my signature in presence of two witnesses.
